Members of Victorian Labor's socialist left faction have been in secret discussions with the right about a potential leadership spill against Premier Jacinta Allan, News Corp newspapers reported on Thursday.
The premier, who has the lowest approval rating of any state leader in the nation at minus 37, said she was not focused on "anonymous gossip" from a "few scallywags out there that might need a bit of a cuddle".
Ms Allan said she was confident she would survive as premier until Victorians head to the polls in November.
"I've got great support from my strong and united Labor team," the Bendigo East MP told reporters on Thursday.
Former Labor campaign strategist turned pollster Kos Samaras called the leaking of backroom chatter "foolish".
"They've been at this months," the RedBridge director told AAP.
"The polling numbers are not great, but I don't think the solution is running out there and doing these attempted drive-bys."
A RedBridge Group/Accent Research poll published earlier in March showed Labor's primary vote had dived to 25 per cent.
But with a similarly poor primary vote of 28 per cent and support for One Nation climbing to 24 per cent, the coalition still faces an uphill battle to net the 16 seats required to form majority government.
White-anting Labor figures were "delusional" if they believed rolling the premier would fix the party's electoral problems, he said.
"Her satisfaction ratings are connected to the government," Mr Samaras said.
"If they want to fix this, you're going to have to work together as a team."
A move to oust Ms Allan as leader has no chance of success without some support from the socialist left faction, which she is a member of and holds a majority within the Labor caucus.
Transport Infrastructure Minister Gabrielle Williams, who hails from the same faction, is viewed as a possible replacement.
She denied knowledge of any discussions behind the scenes to install her as leader or that she was "doing the numbers".
"It's idle gossip and we pay no attention to it," Ms Williams said.
Deputy Premier Ben Carroll, a senior member of Labor's right, denied he was plotting a tilt for the top job and categorically said Ms Allan would lead Labor to the next election.
Police Minister Anthony Carbines said the premier always had his backing, while Treasurer Jaclyn Symes said the caucus was solid.
Victorian Labor has not changed its leader this close to an election since March 1999, when John Brumby resigned following mounting pressure.
Steve Bracks was picked as his replacement and led the party to an "unwinnable" election victory later that year.
